SASH-BALANCE.

SPECIFICATIOEN forming part of Letters Patent No. 2 82,367, dated July 31, 1883,-

.Application filed May 21, 1883. (ModeL) To all whom it may concern:

Be it known that I, CALVIN 0. POWER, a citizen of the United States, residing at West Newton, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Sash-Holder, of 'which the following is a specification, reference being had tothe accompanying drawings.

This invention relates to sash-holders; and it has for its object'to provide means whereby the sash can be raised and lowered by the use of one hand only, and canbe held at any height desired.

It consists in certain improvements in the construction and combination of devices hereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying drawlngs, Figure 1 is a front elevation of a Window equipped with my improved sash-holding device. Fig. 2 is a vertical section of Fig. 1; Fig. 8is a detail iew of the bracket, and Fig. 4. is a detail --view of the T-shaped piece and catch.

Like letters refer to corresponding parts in all the figures.

Referring to the drawings, A designates a bracket attached to the upper part of the lower sash, B. This bracket is formed ofa basepiece, (I, attached to the sash, side walls a,

erected on the base-piece some distance apart,

of a wooden roller, 0, having a rubber band,

a, secured around. the circumference of the;

same, said band being serrated or grooved on its outer surface, so as to form teeth, which bite againstthe upper sash, and thus serve to more securely retain the lower sash in position when raised. A spring, D, is coiled around the journals of the eccentric, one end I of the spring being secured in the front piece,

a, the other end abutting against a shoulder,

(1, formed on the roller of the eccentric.

the shoulder serves to force the eccentric outward against the upper sash.

E designates a cord connected to the eccen- As I will be seen, the pressure of the spring against 5 5 tric, then passing through an opening, 6, in the back piece of the-bracket down to a thumbcatch, F, to which it is likewise connected. This catch is formed with an eye, f, by means of which it ispivoted to the side walls, 9 g, of the T-shaped piece G, which is secured to the bottom end of the lower sash. The projecting lip h of said piece G is rounded underneath to form a hold in raising the sash. The upper edges of the side walls, are rounded in front, as shown, and the inner surface of the thumb-. catch, on each side of eye f, is also rounded, so as to work readily in conjunction.

The operation of my devices can be readily understood from i the foregoing description, taken in connection with the annexed draw ings. The cord E is always kept tight, so that by depressing the thumb-catch the least degree will turn the eccentric. Whenit is desired to raise the sash, the forefinger is placed under the lip h, and then, by moving or depressing the thumb-catch downward by means of the thumb, the cord will be pulled, causing the eccentric to turn. This turning of the eccentric withdraws it from contact with the upper, sash, and thus the lower sash can be raised or lowered without encountering any obstacle to its movements. When it is desired to hold the sash at any particular point, the operator merely withdraws the pressure on the thumbcatch, the eccentric returning ittoits former position, the lower sash being held by the contact of the serrated band of the eccentric against the upper sash.

Heretofore sash-holders have been fastened on the side of the sash, which necessitated the use of one hand to manipulatethe'sash-holder and the other hand to raise the sash, and, besides, many of them are so arranged that the sashcan only be secured at two or three differentVheights. By my construction I obviate the above disadvantages, since by the use of one hand I can raise and lower the sash or hold it at any desired point.

In lieu of forming the bracket A of four separate parts, I can form it from one piece by cutting out the U shaped passage or opening a".

The operation is very simple, yet it is effective in results. The construction is durable and inexpensive, besides possessing other advantages of minor consideration.

It is obvious that various modifications can be made in my device Without departing from the spirit or scope of my invention.

Having thus described my invention, I claim- As an improvement in sash'-ho1ders,abracket secured to the upper part of the lower sash,

and a spring-pressed eccentric journaled in said bracket, in'combination with a T-shaped piece, G, secured to the bottom end of the said sash, a thumb-catch, F, pivoted in the upper portion of thepiece G, alip, h, projectingfrom
